CVE-2025-4704 is a SQL Injection vulnerability identified in version 1.13 of the PHPGurukul Vehicle Parking Management System, specifically within the /admin/edit-category.php file. The vulnerability arises from improper sanitization or validation of the 'editid' parameter, which is manipulated by an attacker to inject malicious SQL code. This flaw allows an unauthenticated remote attacker to execute arbitrary SQL commands on the backend database without requiring user interaction or privileges. The vulnerability is classified as medium severity with a CVSS 4.0 base score of 6.9, reflecting its network attack vector, low attack complexity, and no required authentication or user interaction. Exploiting this vulnerability could lead to partial compromise of confidentiality, integrity, and availability of the database, such as unauthorized data disclosure, modification, or deletion. Although no public exploits are currently known in the wild, the vulnerability has been publicly disclosed, increasing the risk of exploitation. The lack of available patches or mitigations from the vendor further elevates the urgency for organizations to implement compensating controls. The vulnerability affects a niche product used for vehicle parking management, which typically manages categories of parking slots or vehicle types, indicating potential exposure of sensitive operational data or user information stored within the system's database.

For European organizations using PHPGurukul Vehicle Parking Management System version 1.13, this vulnerability poses a significant risk to the confidentiality and integrity of their parking management data. Successful exploitation could allow attackers to extract sensitive information such as user credentials, vehicle details, or payment records, potentially leading to privacy violations under GDPR. Additionally, attackers could alter or delete critical data, disrupting parking operations and causing service outages. This disruption could impact facilities management, commercial parking services, or municipal parking authorities, leading to financial losses and reputational damage. The remote and unauthenticated nature of the attack increases the threat level, especially for organizations exposing the admin interface to public or semi-public networks. Given the critical role of parking management in urban infrastructure and commercial environments, exploitation could also have cascading effects on physical security and operational workflows.

Since no official patches are currently available, European organizations should implement immediate compensating controls. These include restricting access to the /admin/edit-category.php endpoint by IP whitelisting or VPN-only access to limit exposure to trusted users. Employing web application firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'editid' parameter can provide effective protection. Conduct thorough input validation and sanitization on all user-supplied parameters, especially 'editid', to prevent injection attacks. Regularly audit and monitor database queries and logs for suspicious activity indicative of exploitation attempts. Organizations should also consider isolating the affected system within segmented network zones to minimize lateral movement risks. Finally, maintain up-to-date backups of the database to enable recovery in case of data tampering or loss. Engage with the vendor or community to track the release of official patches and apply them promptly once available.
